I have a DNA-500 - admittedly not a 125, but somewhat similar McC "house" sound, if you will.
My first preamp match was a VAC STD LE which I got for a little over $2K, used. The synergy was excellent, and this tube preamp has all the features you are looking for. Great sound, plus the pre is built like a tank, with the best support in the business, IMO, by Kevin Hayes. Excellent value as well. Many have successfully matched VAC gear with McCormack amps (and have big smiles on their faces). Worth a listen if you can find this pre..........
